Machine for making bricks



SAMU-EL B. BRU SSTAR, OF KENSI-INGTON, PENNSYLVANIAw i i Y MACHINE FOR MAKING BRICKS.

i Specification of Letters Patent No. 693, dated Apri1'14, 1838.

To 'all whom t mag/concern Be it known that I, SAMUEL B. BRUssTAn,

of the Kensington district, ofthe Northern i Liberties, Philadelphia county, State of Pennsylvania, have invented a new and use ful machine for making bricks, calledV Brusstars self-feeding, revolving, trundling, shearing, sanding, and brick pressing and clay tempering machine, which is described as follows, reference being had to the annexed drawings of the same making part of this specification.

This `machine consists of a post A, Figure 1, planted in the ground of suliicient strength Vfor the purposes hereafter mentioned. Around this post is constructed a circular foundation B of timber or stone about four feet wide and one foot deep, the diameter vof the inner circle being about twenty-two feet, within which is formed a horse track C of about twenty feetdiameter. Upon i this Vfoundation are laid pieces `of timber or sleepers, each about 18 inches long, 1 inch wide, and 2% of an inch deep, setedgewise, 'with their inner ends flush with the inner circle and about 7 or 8 inches apart, radiatingV from the center o f the circle. Upon these pieces of timber is. formed a circular trough D 18 inches wide and about 3 inches deep. The'sides of this trough `consist of circular rails set upon the before mentioned timbers. In this trough the clay is tempered and is therefore called fthe tempering trough. The outer ends of the sleepers or the ends fartherest from the center of the circle serve as stops for the mold. The spaces 1 1 l between them answer for the discharge of accumulated clay into the center. Outside of the tempering trough is another circular trough E about 10 inches wide and 2%; inches deep under which the molding is performed; this is called the molding trough. Under this` trough are placed onedge wedge shaped pieces or partitions about 20 inches apart forming chambers for the molds. In the molding trough is thrown the clay for making the bricks. p

The molds F, Figs. 1 and 3, are made of metal containing each four apartments for four bricks having a handle on one side by which it is drawn out from and pushed into the chambers, under the molding trough through spaces formed in the rail, forming the outer edge of the trough. Only three are drawn. The molding trough all around is furnished with similarly constructed molds.l Qi 'n IOver the circular foundation and base walk is erected a circular platform Grf,l}3`i"g..1,`

upon posts about ten feet high, `framed of suitable timber and covered with thickV plank. On this platform is deposited the clay for the bricks, hauled up an inclined` plane by horses or otherwise,

The upper ends of the posts may yproject abovethe p l platform to form a railing. The center post acts as a Support for the center `of the plat` form. In the platform are two oblong Aopenings H in which are constructed boxes Itof receive the clay, made flaring downward and projecting below vthe platform Va sufficient distance; the bottom of each moving on pivots J by means of levers K for discharging the clay. Around the post is put a loose collar L `flanged at its lower end, to which are fastened four or more arms M radiating 'from the center, having on the fouter end 'of' :each a wheel N about feet diameter,` and il foot thick, weighing above 4 or 500 Three of. these wheels revolve in` the inner or tempering trough for temper- A ing the cla-y. The fourth wheelN revolves t Y pounds.

in the outer or molding trough for molding and pressing the bricks having flanges fto turn on the rails P to prevent its pressing upon the edges of the molds so as to destroy them. Y

In front of one `of the wheels of the inner trough is a fifth or smaller wheel Q,

which acts as a regulator and. feeder. See Figs. 1 and 3. Over and around these two wheels is constructed a` traveling' hopper R to receive the clay from` thedischarging lboxes I. To a suitable framing on .the arms and between the several wheels' are attached plows S placed in the inner trough forturning the clay to thecenter thereof to trough-to be let down or raisedby means` of a lever U, cord c, and pulley p or otherwise. The forward end is made'of a triangular shape so as to throw the clay to the left. Over the outer .trough i and attached to said frame is a strike shear V` Figs. 1 and 5 to strike the brick and throw trough; it is let down or raised bymeans back the surplus clay into the tempering y l Y Z for conducting the sand to the moldsthe lower and outer end'of which is covered with'a sieve, particles of the sand.

The horses for operating the machine 'areV attached to the arms and travel around in the horse track.V l Under vthe molds is a false bottom Fig. 7 for keeping the molds up even with the tops of the partitions; it is made of a wedge shape on the under side in order to force the molds up even with the bottom of the molding trough.

Behind the wheels are yScrapers s, Fig. l. fastened to the frame for keeping the wheels clean.

V'Operation: The clay is hauled up and deposited upon the circular platform Gr. It is then thrown into the boxes I with movable bottoms; the bottom of the box over the feeding wheels is turned by the levers K attached to it which empties the clay into the traveling hopperfrom whence it passes betweenthe wheels N, Q, into the tempering trough D in an even layer oven which the hind wheel turns and lattens it o-ut*as the horses move around with the lwheels N; itis then met by one of the tempering trough and from its triangu-V lar'shape and forward movement turns the clay over into the molding trough E. v From this trough it is pressed into the molds by the pressing wheel N revolving lin said trough-the molds having previously been a to arrest the largerVK inserted into the chambers to Vwhich they belong. The shear and striker V is then let down into the molding trough', which,

Vas it moves forward strikes the brick and turns the surplus clay again into thei tem- Y pering trough `D. The molds are then drawn out from the chambers, the bricks off-borne, andthe empty molds replaced.

VYWhen the shear and striker are not in use they are raisedV from the troughs and secured by placing the levers against pins 3 or stops in the frame.

The sanding of the molds is performed by means of the'inclined tube Z and screen a before described Figs. l and 6.

On the arrival of the traveling hopper R beneath the other discharging box I the same operation takes place as that before -ing the brick and turningk the surplus ela-y back into the temperingY trough-the sanding apparatus-the arrangement of the sliding molds and the chambers into which they are inserted under the molding troughthe spaces formed under the tempering trough through which any accumulated clay may be discharged into the horse *walk-- also the discharging boxes-the whole in combination as before described.
